We can make the growfs and makefs binaries conditional because we know if we'll need them. Also move the cryptsetup generator to the luksroot so it's not included when not needed. We drop some generators altogether: systemd-getty-generator because we don't have getty anyway in stage 1, systemd-system-update-generator because we don't use that logic in NixOS and systemd-veritysetup-generator because stage 1 has no veritysetup support (yet) and if it had, we still wouldn't want to include the generator unconditionally.
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at https://nixos.org/nixos and in the manual in doc/manual.
